Thanks Ivan, this is helpful. I'll do some more research. It would be nice
to have an Rcpp standard/recommended way to do this. I don't want to have a
non-standard ./src or ./data folder structure for my Rcpp package, but
these are the two relevant folders in my original repository. Maybe with
some sort of synlinking I could achieve this 'custom' folder/file mapping.

Ideally, it would be nice to be able to pull the files from the
source repo using a tag/hash so that the only code change in the Rcpp
repo would be that reference rather than all the changes to the
shared source.
I've been using Git submodules for this purpose:
https://codeberg.org/aitap/Ropj/src/branch/master/src
https://git-scm.com/book/en/v2/Git-Tools-Submodules
Every time the upstream changes I have to update the commit pointer in
my repository too, but other than that, it's been working fine. My
.Rbuildignore filters out all the unnecessary files included in the
upstream repository, leaving only the relevant source code in the
resulting source package.
The resulting repository must be cloned with --recurse-submodules (or,
if forgotten, must be initialised with git submodule update --init);
further updates to the tracked commit pointer must be applied with git
submodule update. If the referenced repository becomes unavailable, it
will be impossible to build the package.
